SNOWPLOW Application filed April 30,

The present invention is directed to an attachment for trucks, designed for the purpose of removing snow deposited along the sides of roadways and streets by the action of the 5 conventional blade plow.

The structure involved in one of the as semblies includes a scoop adjustable in width and designed to direct the accumulated snow upwardly into a fan casing from which it is projected laterally by suitable impellers or fan blowers driven from a source of power carried by the truck.

Reference will be had tothe accompanying drawings forming a part of this specification and wherein like characters of reference designate corresponding parts throughout the several views, in which: 1

Fig.1 is a plan View; v

Fig. 2 is a side elevation; and

Fig. 3 is an end elevation.

In the present disclosure a truck is illus-- trated having the forwardly mounted motor A for propelling same and the rearwardly mounted motor B for driving the fans.

i The usual blade type of plow is illustrated at C positioned on the frame D and operates to force the snow in piles along the longitudinal edges of the road. Such deposits of snow are, in many instances, of such weight and 'bodv that further movement from the road is impractical, unless some. special means is provided for the removal of same. The present invention comprehends an assembly placed upon either side of the truck and rearward of the front blade plow C whereby the scoop element will engage the roadside deposits caused by the front plow. In the present illustration, the auxiliary snow handling assembly comprising this invention is positioned at the ex reme rear end of an extended chassis but may be located at any desired point rearward of the plow C.

Each snow removing element includes a scoop comprising a main body portion E and the pivoted portion E which permits lateral adjustment of the parts and the widening ofv the engaging; edge e for'the reception of deposits of any proposed width whichwill be. determined by the snowfall. The scoop memfree of the ro'adbed as desired.

casing F in which is located the fan or blower G. The fan casing is mounted loosely on the shaft section H on which the fan G is fixed and by means of which the latter is driven 1 through suitable gearing in gear boxh from power derived through the shaft J from the engine B. By this arrangement thescoop can be adjusted vertically with respect to the ground for use in conjunction with various types of roadbeds or may be'moved entirely The adjustable scoop E, E permits a more compact as semblvof the device when not in use. A

suitable hoist K is shown for use in conjunc- "tion with the elevation of the scoop although other desirablemeans may be employed.

. It will be noted that the scoop comprising the sections E, E extends rearwardlya suflicient distance and gradually decreases in width, terminating eventually in the casing Fin which is located the fan or blower G. In order to comprehend a more compact structure the forward wider portion ofthe scoop may be mounted to'swing upwardly against the vehicle body, as shown in Fig. 3, upon the hinges'L, whereby the width. of the assembly maybe materially reduced.

What I claim is:

p 1. In combination with a motor vehicle, a snow plow carried by the front end of said motor vehicle, an inclined scoop carried by said motor vehicle rearward of said snow plow a blower arranged in conjunction with said scoop, and adjusting means for said scoop.

2. In combination with a motor vehicle, a snow plow carried thereby and adapted to force snow from its path laterally of the motor vehicle, a scoop positioned rearward of the snow plow for gathering the snow accumulated by same, a blower for forcing the snow'gathered by the scoop outwardly from the motor vehicle, and means for adjusting "the scoop.

ber'extends upwardly and terminates in a fan in that the scoop which is vertically adjustable is provided with a hinged section which permits adjustment of the cutting edge.

5. vIn combination with a motor vehicle, asnow plow carried thereby and adapted to force snow from its path laterally of the motor vehicle, a scoop positioned rearward of the snow plow including an inclined portion comprising a plurality of hinged overlappling sectlons, a guide-Way forming a continuation of the scoop and terminating in a blower oasing,'a blower arranged in said casing, means for driving said blower, and means for adjusting said scoop. 5

In testimony whereof I aifix my signature.
